This product uses a double decomposition method, complies with national chemical industry standards, and serves as an efficient heat stabilizer and low-temperature processing lubricant.
It is widely used in non-toxic stabilizers for polyvinyl chloride, lubricants for polyethylene, ABS, and SAN resins, as well as release agents for transparent products.
Physical and chemical properties: white powder, insoluble in water but soluble in alcohol, decomposes in strong acids, and has hygroscopicity in the air.
Technical specifications: HG/T 3667-2000
Advantages of this product
1 High product purity, low free acid value, good lubrication.
2 Excellent lubricity improves production efficiency, enhances product quality and quantity, and reduces overall costs for enterprises.
3 In hard plastic products, it can increase the coagulation speed and can also be used in non-toxic soft films for food packaging and medical devices, while having stabilizer effects and good long-term stability.
4 Widely used abroad to improve the heat resistance of plastics, enhance weather resistance, initial coloring, and permeability, replacing toxic stabilizers with similar properties.
Applicable Scope
This product is a stabilizer and lubricant for polyvinyl chloride, suitable for non-toxic food packaging and soft films for medical instruments. It acts as a halogen absorber in polyethylene and chloroprene to eliminate the adverse effects of residual catalysts on resin color and stability.
This product is also widely used as a lubricant for polyolefin fibers and molded products, a waterproof agent for waterproof materials, and can be used as a lubricant and release agent for thermosetting plastics such as phenolic and amino plastics, thickening agent for lubricating grease, waterproof agent for textiles, and flatting agent for paints.
